Enum LayerConfiguration.Feature

Enum Constant Detail

• DETAIL_RENDERING

  public static final LayerConfiguration.Feature DETAIL_RENDERING

  Additional rendering details like buildings. Only used for the MapView. When not set, the data will be excluded when downloading offline regions or prefetching areas that contain such data. However, during online usage such data may still be downloaded into the cache and shown. Increase of 11-16% is to be expected for map size, in case of enabling this feature.

  Feature enables following OCM layer groups:

  • "detailed_rendering"

• NAVIGATION

  public static final LayerConfiguration.Feature NAVIGATION

  Map data that is used for map matching during navigation. When not set, navigation may not work properly when being used offline. Increase of 5-7% is to be expected for map size, but pay attention, that this feature is depended on other layer groups (e.g. routing), so, in total is takes about 21-29 % of map size.

  Feature enables following OCM layer groups:

  • "interop"
  • "rendering"
  • "navigation"
  • "routing"

• OFFLINE_SEARCH

  public static final LayerConfiguration.Feature OFFLINE_SEARCH

  Map data that is used to search. When not set, the OfflineSearchEngine may not work properly when being used offline.

  Feature enables following OCM layer groups:

  • "rendering"
  • "routing"
  • "search"

• OFFLINE_SEARCH_GLOBAL

  public static final LayerConfiguration.Feature OFFLINE_SEARCH_GLOBAL

  Map data used for global search indexing. This feature enables searches across broader geographic areas and improves both performance and accuracy by leveraging global search indices. By default this feature is disabled.

  Enables HERE SDK to use the enhanced offline search algorithm when OFFLINE_SEARCH_GLOBAL is present in LayerConfiguration.enabledFeatures and downloaded map regions exist with required OCM layer groups listed below. Note: Currently, this algorithm supports only offline maps stored in persistent (protected) storage.

  To prevent excessive map size growth, it is recommended to enable only one of OFFLINE_SEARCH_GLOBAL or OFFLINE_SEARCH at a time.

  Enabling this feature increases the size of downloaded map regions by approximately 11–16% when enabled via LayerConfiguration.enabledFeatures.

  Feature enables following OCM layer groups:

  • "search_global"
  • "search_data"

  Note: This is an alpha release of this feature, so there could be a few bugs and unexpected behaviors. Related APIs may change for new releases without a deprecation process.

• OFFLINE_ROUTING

  public static final LayerConfiguration.Feature OFFLINE_ROUTING

  Map data that is used to calculate routes. When not set, the OfflineRoutingEngine may not work properly when being used offline. Increase of 12-16.5% is to be expected for map size, but pay attention, that this feature is depended on other layer groups (e.g. navigation), so, in total is takes about 33-45 % of map size.

  Feature enables following OCM layer groups:

  • "rendering"
  • "navigation"
  • "routing"
  • "interop"
  • "car_offline_routing"

• RENDERING

  public static final LayerConfiguration.Feature RENDERING

  A basic set of rendering features such as carto POIs. Increase of 16-22% is to be expected for map size, but pay attention, that this feature is depended on other layer groups (e.g. navigation), so, in total is takes about 21-29 % of map size.

  Feature enables following OCM layer groups:

  • "rendering"

• TRUCK

  public static final LayerConfiguration.Feature TRUCK

  Map data that is used to calculate truck routes. When not set, the OfflineRoutingEngine may not work properly when being used to calculate truck routes. It is also used for map matching during truck navigation. When not set, truck navigation may not work properly when being used offline. Online truck navigation will still work when the device has an online connection. Increase of 0.7-1.1% is to be expected for map size, in case of enabling this feature.

  Feature enables following OCM layer groups:

  • "truck"
  • "long_truck_offline_routing"
  • "truck_offline_routing"

• LANDMARKS_3D

  public static final LayerConfiguration.Feature LANDMARKS_3D

  Map data that is used to render textured 3D landmarks. When not set, the data will be excluded when downloading offline regions or prefetching areas that contain such data. When the landmarks layer is set to be visible for a MapScene, 3D landmarks will still be visible during online usage. Increase of 2-3% is to be expected for map size, in case of enabling this feature. Disabled by default.

  Feature enables following OCM layer groups:

  • "landmarks"

• EV

  public static final LayerConfiguration.Feature EV

  Offline map data for EVChargingStation.
